Prophysaon, common name taildropper slugs, is a genus of air-breathing land slugs, terrestrial pulmonate gastropod mollusks in the family Arionidae, the roundback slugs.
These slugs can self-amputate (autotomy) a portion of their tail.[2] This autotomy has been observed in the species Prophysaon andersoni.[3]
Distribution
This genus of slugs occurs in North America, including California and Oregon.
